Abstract

A surfboard for use by riders on bodies of water is disclosed having first and second apertures extending through the surfboard from the bottom side to the top side, angled such that each aperture has a first opening on the bottom side and extends at an angle toward the tail end of the surfboard to a second opening on the top side of the surfboard. A first channel disposed within a portion of the bottom side of the surfboard, terminating at the first opening of the first aperture, and a second channel disposed within a portion of the bottom side of the surfboard, and terminating at the first opening of the second aperture, the first channel and second channel separated by a raised portion of the bottom side, thus defining a trimeran profile on the bottom side, the trimeran profile having a first and second rail, and a center portion.

Claims

exact text as granted — not AI-modified
1. A surfboard having a length defined by a front end and a tail end, and a thickness defined by a bottom side and a top side, the surfboard comprising:
 first and second apertures extending through the surfboard from the bottom side to the top side, the apertures angled such that both apertures have a first opening on the bottom side and extends at an angle toward the tail end of the surfboard to a second opening on the top side of the surfboard, the second opening closer to the tail end of the surfboard than the first opening, the second opening closer to the tail end of the surfboard than the first opening, further comprising a first channel and a second channel, the first channel disposed within a portion of the bottom side of the surfboard, and terminating at the first opening of the first aperture, and the second channel disposed within a portion of the bottom side of the surfboard, and terminating at the first opening of the second aperture, the first channel and second channel separated by a raised portion of the bottom side, thus defining a trimeran profile on the bottom side, the trimeran profile having a first rail, a second rail, and a center portion. 
 
   
   
     2. The surfboard of  claim 1 , further comprising a third channel disposed on the top side of the surfboard, behind the first aperture and extending toward the tail end of the surfboard. 
   
   
     3. The surfboard of  claim 1 , further comprising a fourth channel disposed on the top side of the surfboard, behind the second aperture and extending toward the tail end of the surfboard. 
   
   
     4. The surfboard of  claim 1 , wherein the first aperture and second aperture are located at substantially equal distances from the tail end. 
   
   
     5. The surfboard of  claim 1 , wherein second opening of the first opening of the first aperture and the second opening of the second aperture are located approximately 12.5 inches from the tail end. 
   
   
     6. The surfboard of  claim 1 , wherein the surfboard further comprises at least one skag attached to the bottom side proximate to the tail end. 
   
   
     7. The surfboard of  claim 1 , wherein the top side incorporates a curvature, the curvature defined by the front end raised above the center of the top side, tail end raised above the center of the top side. 
   
   
     8. The surfboard of  claim 1 , wherein the first channel and second channel begin approximately 18.5 inches from the front end. 
   
   
     9. The surfboard of  claim 1 , wherein the surfboard comprises a foam core covered by an outer shell of epoxy, fiberglass and resin. 
   
   
     10. The surfboard of  claim 1 , further comprising a stringer, the stringer incorporating a wooden spline in the center of the width of the surfboard and extending through a portion of the length of the surfboard. 
   
   
     11. The surfboard of  claim 1 , wherein the first aperture and second aperture are disposed at an angle, the angle sufficient to provide a vertical clearance between the bottom side and top side. 
   
   
     12. The surfboard of  claim 1 , wherein the tail end comprises a pin tail design. 
   
   
     13. The surfboard of  claim 1 , wherein the tail end comprises a diamond tail design. 
   
   
     14. The surfboard of  claim 1 , wherein the tail end comprises a round tail design. 
   
   
     15. The surfboard of  claim 1 , wherein the tail end comprises a fish tail design. 
   
   
     16. The surfboard of  claim 1 , wherein the tail end comprises a bat tail design.
